SPECIFICATION forming part of Letters PatentNo. 714,576, dated November25, 1902.

. Application filed July 21, 1902.?

To all whom it may concern.-

Be it known that I, ELLIS GRABER,machineruler and machinist, a subjectof the King of Great Britain, residing at 33 Ohandos road,

Tunbridge Wells, in the county of Kent, England, have invented a new anduseful Improvement in Ruling-Machines, (for which I have filed anapplication for Letters Patent in the United Kingdom of Great Britainand [0 Ireland, numbered 26,362, and hearing date the 24th day ofDecember, 1901,) of which the following is a full and completespecification.

This invention relates tohruling-machines in which the sheets of paperto be ruled are passed under the ruling-pens by means of a travelingendless apron; and it has for its objects, first, to arrange thetraveling end less aprons so that they cannot possibly become marked bythe ruling-pens when sheets of paper are not passing beneath the pens,

second, to increase the length of drying-surface without increasing thelength of the machine; third, to provide for ruling both sides of thesheets of paper; fourth, to provide for bringing the sheets of papersquarely up to the ruling-pens; fifth, to provide for the travelingendless aprons running truly and square with the ruling-pens; sixth, toprovide for altering and adjusting the positions of the pen-beams, and,seventh, to provide for the pens being automatically broughtinto line asthey are secured to the beam, and, lastly, to produce ruled work with aless cost and in a more expeditious manner than has 5 heretofore beenpracticable. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure 1, Sheet No. l, is a View inside elevation showing the general construction and 40 arrangement. Fig.2, Sheet No. 2, is a diagrammatic view showing the arrangement of one ofthe endless traveling aprons and its threads. Fig. 3, Sheet No. 3, is adiagram matic view showing the arrangement of the 5 other endlesstraveling apron and its threads. Figset and 5,Sheet No. 4, are brokenviews, in

partlyin section, of part of the machine. Figs. 6 and 7, Sheet No. 6,are broken views,

in side elevation and plan, respectively, showing the device forbringing the sheets of paper squarely up to the ruling-pens for thesecond ruling. Figs. 8 and 9, Sheet No. 7, are broken views in sideelevation and plan, respectively, showing my improved lay-boy.

In my improved machine both sides of the paper can be ruled at one turnthrough the machine. Also two operators can feed simultaneously eitheron two distinct jobs or on the same job, thereby doing the Work of twodouble machines; For instance, one. opera- 6 tor can feed the paper forfeint lining and the other for down or cross lining at the same time, sothat once the machine is prepared and set running the work is at onceproduced. ready for binding, packing, &c.

A machine constructed according to the present invention has theadvantage that without increasing the length of the machine the travelavailable for drying the ink has i It also dispenses with most of theoverhead gear, whereby better light on the work is obtained, and,moreover, as

both pen-beams are arranged on the same level the usual height of asingle machine is not increased, thereby doing away with the so-calledtwo-deckers. As about one-half of the top of the machine is availablefor piling paper on, there is a considerable economy in space.

The frame a carries two distinct ruling apparatus, each of whichconsists of a pen-beam,

an inking device, a traveling apron, and traveling threads to keep thesheets of paper in contact with the aprons, while common to both suchapparatus is the driving mechano ism, the cam mechanism for operatingthe inking device, the feeding-table, the lay-boy, and thedelivery-table.

The two traveling aprons Z) and c are arranged as shown in Figs. 2 andReferring 5 to Fig. 2, the apron b, which is endless, lies over twohorizontally-arranged rollers b and b at the front end of the machine.It then passes around another small roller b located below the roller band then up over a large 10o roller b the periphery of which is on aline with the two rollers b and biwhereby a loop or .mediateguide-roller b to a similar roller 6 at the back end of the machine,around the said roller, and forward again over an intermediateguide-roller b to another roller 12 atthe roller 1).

front end of the machine immediately above the roller b From this rollerthe apron passes up over another. guide-roller b to the The threads atfor the apron b are arranged as shown in dotted lines in Fig. 2, beingguided by suitable guide-rollers d d, &c. The other endless apron c isarranged as shown in Fig. 3. After passing over rollers c, 0 c and 0arranged in a similar manner to the rollers 19', b b and b to'give aloop or dip to it the apron passes to a roller 0 at the top rear end ofthe machine, around this roller, and over a suitable guide-roller c to aroller 0 located as near to the front of the machine as the first apronb will allow, thence back for a distance about half the length of themachine, around a roller 0 and forward again over the roller 2) of thefirst apron, thence over the guide-roller b also of the first apron I),located under the roller 6, around guide-rollers c to the rollersc. Thethreads e for the apron c are arranged as shown in dotted lines in Fig.3, being guided by suitable guide-rollers e e, 850.

Between the two aprons b and c are endless threads lc. (Shown in dot-dotand dash lines in Figs. 2 and 3.) These not only serve to conduct thesheets of paper from the apron b to the apron 0, but are speciallyarranged, as will hereinafter be more particularly described, to squarethe sheets of paper up before delivering them onto the apron c.

The rollers 17 and 0 by means of which the loops or dips are formed inthe endless aprons or sheets I) and-c, are each mounted in adjustablebearings a, so as to provide a means of adjusting the tension of thesaid aprons.

In order to obviate any undue strain on the endless aprons and also toinsure the various mechanisms acting synchronously, the axles carryingthe rollers b b b 0 c and c are geared positively together by means ofchains and sprocket -wheels, as illustrated diagrammatically on Figs. 2and 3. Y An endless sprocket-chain 03, arranged on one-side of themachine, gears with the under side of a sprocket-pinion 'y, fixed at therear end of the machine on a counter-shaft y, geared with the main shaftzby any suitable form of variable gearing z. The chain x then passesupward and gears with the upper teeth on a sprocket-wheel J0, fixed onthe axle carrying the roller b'fithencepasses to the front end of themachine around an idle sprocket-wheel 00 carried on the axle of theroller b then around sprocket-Wheels x x and 00 fixed, respectively, onthe axles of the rollers 0 b and b returning to the pinion y after firstgearing with the upper teeth on a pinion 'u, fixed on a. counter-shaft'v. A second endless chain 00 arranged on the opposite side of themachine,after gearing with the under side of another sprocket-wheel,fixed on the opposite side of the countershaft 2;, passes upward oversprocket-wheels m a fixed, respectively, on the axles of the rollers cand c and returns to the sprocketwheel on the counter-shaft 1) afterpassing over an idle guide-pulley 00 and gearing with a sprocket-wheel00 carried by the operating-shaft 0 of the lay-boys.

The direction of travel of the chains and the direction of rotationimparted to the rollers are as shown by arrows on the drawings.

In each loop or dip is placed a transverselyarranged plate Z, having oneor more longitudinally-arranged grooves Z in it, over which the rulingis effected. This plate is arranged on a level with or slightly abovethe rollers b b and 0 0 respectively, and also with the feed-table.

The heads carrying the pen-beams and inking devices are so mount-ed withrespect to the loops or dips in the endless aprons that the pens carriedby each bear on or lie over the grooved plate Z, located in the saidloop or dip. This grooved plate is pivoted at the center on a cross-barZ and at each end are slots to enable it to be adjusted at an angle withthe traveling apron. The operative points of the ruling-pens lie overthe longitudinally-arranged groove or grooves Z in this plate, and asthe loop or dip in the endless apron is immediately under this groovedplate the pens can never touch the apron even if no sheets of paper arepassing, so that they can be kept down over the groove or grooves, andthe machine can run continuously with out fear of the endless apronbeing marked by the ruling-pens when the sheets of paper are not passingbeneath them. Thus it will be seen if the operators are not sufficientlycompetent to feed the paper at the high speed the machine is capable oftraveling, owing to the special method of doubling the length of dryingtravel-say, for instance, when two operators are working at the sametime on i one or two jobs and the operator stops or finishes his jobbefore the other-no material harm is done to anything, which is a greatadvantage when the machine is being operated by unskilled persons.

The endless strings d and e employed to keep the sheets of paper incontact with the traveling aprons run on suitable guide-rollers d d,&c., and e e, &c., and are automatically kept at a constant tension byweighted pulleys d and 6 located at the rear end of the machine.

The pen-beam f instead of being pivoted in bearings mounted on the frameof the machine is pivoted on a transverse barf, fixed to pillars f adjustably mounted on the sides of the frame a of the machine, so that thesaid beam can be readily and conveniently lined up with the framewithout any risk of binding the bearings. The lower part g of thepen-slide is extended beyond the upper part and has a raisededge g, withwhich the pens g engage at a convenient distance from their operativeends, which tends to automatically bring and keep them in line, as theyare clamped in the slide.

The striking-gear for stop-rulin g operating by lifting the pen-beamcomprises a lever f carried by the pen-beam f. The position of the leverf with respect to the pen-beam can be varied and adjusted by hinging thelever f to the pen-beam and controlling the movement by set-screwsf f Aset-screwf carried by the lever f and engaging a stop f carried by theframe, is also provided for adjustment purposes. The free end of thelever f is furnished with a rubbing-piece f adapted to contact withremovable and adjustable cam-piecesf carried on the wheel f fixed on theaxle h of the roller 29 It will be understood and seen on reference toFig. 1 a separate striking-gear, arranged precisely as above described,only operated from a cam-wheel fixed on the axle h of the roller 0 isprovided for the second ruling mechanism.

The axles h, carrying the cams which operate the striking and stop-gategears, are geared together by means of sprocket wheels and chains, ashereinbefore described, so that the said cams act synchronously, whichis a matter of importance when the machine is ruling paper on both sidesduring one travel through the machine.

The inking of the pens can be done in the usual way, but preferably bythe device described in the prior patent, No. 609,884, dated August 30,1898. The cam m, by which the controlling device is operated, is mountedon an axle m, carried in bearings formed or fixed to one end of arocking arm n, mounted to rock freely on the axle h. The axle m isgeared to the axle h by means of a spurwheel m and pinion 71 The rockingarm n is connected with the starting-lever U by meansof an eccentric u,whereby the movement of the starting-lever u to stop the machine dropsthe axle m, carrying the cam m, so that it will not engage thecontrolling device, thereby insuring, should the machine be stopped whenthe cam m is in engagement with the ink-controlling device, that thefiow of ink is stopped. The ink-controlling device for both thepen-beams is operated from the cam m by means of two levers 0% m pivotedto the frame at m and m, respectively,

the one end of the lever m or a roller thereon being operated directlyby the cam m, its free end engaging the one end of the other lever mWhose free end is connected to the ink-controlling device of the otherpen-beam. Instead of having a plurality of rubber tubes for each coloredink delivering the ink from the reservoir and nipped by the nipping-barsof the ink-controlling device, as described in the aforesaid priorpatent, a single rubber tube t for each colored ink is used. The tube tdelivers the ink to a pipe or trough t, arranged over and parallel withthe pen-beam, and the ink from said pipe or trough is dis tributed tothe required position for the pens by a series of taps or cocks tcarried by said pipe or trough t. The stop-gates s, in combination withthe striking-gear for stop-ruling, are opened instantaneously by meansof cams j, carried by wheels on the axles h of the rollers b and 0respectively. Levers s, pivoted at s to the frame, each have their oneend adapted to engage their respective cam, while their free ends areconnected by links .9 with arms 3 fixed on axles 3 carried by the frameand furnished with oppositely projecting arms 8 carrying the gates 8.Provision is made for readily throwing the gates out of gear, which maybe conveniently accomplished by simply turning the arms carrying thegates into a 'Vertical position, thereby preventing the leverscontacting with their cams.

Eccentrically-mounted rollers s are provided adjacent to the stop-gatesand over which the endless aprons and threads pass, whereby the apronsand threads at such points may be slightly raised on rotating therollers s in the necessary direction, thereby providing for fineadjustment, so as to enable the gates to stop paper as fine as tissuewithout rucking or wrinkling its edge. Hand-wheels s fixed to the axlesof said rollers 3 are provided to facilitate adjustment of the same, andlock-screws 3 working in slots formed in said wheels, are furnished tolock the rollers in position after the adjustment has been effected.

The feedingtable 1) is mounted. between the two beams, so that the twoparts of the machine can be fed from the same table, the sheets of paperbeing fed from each side, the operators standing opposite each other.This table is provided with guides 19 p at each side, which are capableof being set transversely within certain predetermined limits to providefor any inaccuracy in the cutting of the sheets of paper. In addition tothe side guides p there is also fixed a pair of central guides ptransversely adjustable, so that the sheets of paper can be guided byboth edges. These central adjustable guides are preferably fixed by acentral clamping-bolt or traversing a transverse slot in the board andby a clamp at the front edge; but any other suitable device may beemployed. On this feeding-board a stack of sheets of paper is laid inbetween the guides and simply stroked in between the threads d and theapron 19 passing over roller 1), and by its use a greater output andspeed are obtained, owing to the minimum amount of handling the paperreceives, and it also saves damaging the paper. Provision is made forthe table, with its guides,to be raised for the purpose of inspectingandoiling the interior of the machine by hinging the table at p to theframe a and providing handles 19 on said table.

The endless threads la, (see particularly Figs. 6 and 7,) which receivethe sheets of paper from the apron b and deliver them to the apron c andthreads 6, are carried on grooved rollers k and k The roller k is formedin two parts capable of longitudinal movement on the axle k Set-screws kare provided on each part in order to lock the said parts to the axleafter the required adjustment has been made. The object of thisadjustment is to suit the different sizes of paper passing through themachine. The axle is driven by gearing from the roller 0 or from anyother convenient rotating part in such manner that the threads 70 willtravel at a slightly-greater speed than the threads d e and the apronsbc in order that the sheets of paper may be slightly separated from eachother while traveling on the threads 70 to enable the said sheets to beproperly squared up be fore passing under the second set of rulingpens.This squaring up is effected by so setting or adjusting the roller 70that the threads is incline outward to each side of the machine, asshown, a greater inclination being given for large'sheets of paper thansmall ones, so as to cause the one edge of the sheets of paper travelingthereon to engage the parallel guides a fixed on the frame a. It is tobe understood that the arrangement shown and described is for squaringup two sheets of paper simultaneously, one sheet on each side of themachine. Each sheet must of course only be of such a size as to becarried by the threads inclining in one direction. When it is requiredto square up a sheet of paper of a greater size, the roller 70 must beso adjusted as to cause all the threads to incline in the samedirection. It will thus be seen that the sheets of paper areautomatically squared up before being delivered to the apron c for thesecond ruling.

Lay-boys 0 o are arranged at the rear end of the machine between the twotraveling aprons b and 0 and differ only from the ordinary construction,inasmuch as their feeding-rollers o, 0 0 and 0 are geared up by thesprocket-wheel 00 so as to deliver the sheets at longer intervals thanthey are received by them, and the inner side guides are made adjustableto suit different widths of sheets.

The side guides 0 0 are carried by the feed-rollers 0 0. The former,together with the feed-rollers 0 are capable of being clamped to a fixedtransverse bar 0 The feed-rollers 0 arranged beneath the rollers 0 areso mounted on the shaft 0 as to be free to slide thereon and also torotate therewith. The rollers 0 are kept in gear with the rollers 0 byforming grooved collars on the former, adapted to be engaged byprojections carried by the guides 0 The delivery-table r is providedwith adjustable transverse fixed stops 1' and longitudinal fixed stops'r The latter are preferably carried by the movable guides 0 of thelay-boys, so as to make the one adjustment serve two purposes and alsoeconomize space.

The stops r r are given a reciprocating motion, so as to knock up eachsheet square as it is delivered on the table. The stop r is reciprocateddirectly by means of eccentrics r mounted on the shaft 0 communicatingmotion to shafts r carrying the stop W. The stops r are alsoreciprocated from the motion derived from the shafts r through themedium of links and bell-crank lever r". The stops 7' are so formed orhinged as to enable them to be turned down in order to facilitate theremoval of the ruled sheets from the table.

A table g, on the rear part of the machine, is provided whereon theruled paper after removal from the table r is stacked. A rack q is alsoprovided between the supports a of the thread-carrying guide-rollers 01e, adapted to hold a series of pen beams when not in use;

The starting and stopping of the machine can be effected from eitherside by means of levers it, connected to a shaft M, which carries theeccentric it, hereinbefore referred to. The shaft to is connected in anysuitable manner with a belt-shifting fork acting on the main drivingbelt, engaging pulleys on the main shaft 2'. The eccentric u, not onlyoperates the arm n of the ink-controlling device, but also looks theshaft a in its position, thus locking the belt-shifting fork on the fastor loose pulley, and so preventing the machine from startingaccidentally.

In operation the action is as follows: The sheets of paper are laid onthe feeding-table p between the guides p p and are stroked in one by onefrom a pile between the threads 61 and the apron b, and, passing overthe roller 1), they are nipped by the endless threads running around thesaid roller and carried under afeed-roller b. As soon as the edge of thesheet of paper passes over the groove in the transverse plate the pensyield onto the surface of the sheet of paper, and by the travel of thesheet it becomes ruled. Thus the first side is done. From thence thesheet is carried on by the guide-rollers and endless strings or threadsaround the various pulleys supporting and guiding the apron b for dryingthe ink. The sheet of paper is then delivered (by this time the ruledside is face downward) onto the threads is, and is thereby automaticallysquared before it passes onto the second apron c and between it and thethreads 6 under the feed-roller c and the second set of pens for rulingthe other side. The drying is repeated by the travel around the variouspulleys supporting and guiding the apron c. The sheet is thenautomatically delivered by the lay-boy perfectly dry and square onto thedelivery-table.
